Frantisek Kovarik and co-workers have recently published a new article with the description of two new species of Chaerilus Simon, 1877 (Chaerilidae) from Vietnam.

Chaerilus granulatus Kovarík, Lowe, Hoferek, Forman & Král, 2015

Chaerilus longimanus Kovarík, Lowe, Hoferek, Forman & Král, 2015

Abstract:Chaerilus granulatus sp. n. and C. longimanus sp. n. from Vietnam are described and compared with other species of the genus. Both species are characterized by: median eyes present; movable finger of pedipalp with 7–9 rows of granules; total length of adults under 30 mm; male differing from female in having pedipalp chela much narrower and longer. The two new species are differentiated by: ventral sides of sternite VII are smooth in C. longimanus sp. n. and granulated in C. granulatus sp. n. Adults of both sexes of C. granulatus sp. n. and C. hofereki Kovařík et al., 2014 were raised from birth and their exuviae were retained and compared to the mature adults. Hemispermatophores of C. granulatus sp. n. and C. hofereki were extracted and illustrated. Karyotype of male holotype of C. granulatus sp. n. consists of high number of chromosomes (2n=96).
